There are many nano-parts composted and integrated to be parts of a human body, which can be investigated and improved by using nanotechnology. Nano-medicine has become the important subject of the world of health and beauty today, in which much of the research in this field has become the challenge and basis for our future developments. In this book, the nano-device known as a PANDA ring resonator is designed and used to form the applications in medicine, especially, nano-medicine. By using the practical optical device and thin film technology, the designed devices and systems can form the human body embedded device, which can be used as the human body embedded devices. There are three major areas of research subjects: drug delivery, molecular diagnosis and therapy and artificial organs integrated to be a monograph book.
